Specification of Letters Patent.

Patented Sept. 19, 1905.

Application led May 16,1904. Serial No. 208,210.

To [all whom/ if Netty concern.-

Be it known that I, GEORGE P. REUHL, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented-,certain new and useful Improvements in Coating-Machines, of which the following is -a specification.

It is the object of my invention to provide a new and useful coating-machine adapted for applying' a cover or coating in highly-divided state to stock passing through the machine.

In my improved device I provide a feedingtable upon which stock is fed, upon preferably both sides of which atomizing apparatus is arranged for playing upon the stock while being fed through the machine. The atomizing apparatus is preferably adjustable to height to angle with relation to the direction of the feed and to angle transversely of they ther, in providing a casing through which thestock to be operated on is arranged to pass either side of the stock arranged to play upon the stock while passing through the casing, and, further, in the parts and in the construction, arrangement. and combinations of parts hereinafter more fully described and claimed.

In the drawings, Figure 1 is a side elevation of my improved device, partly broken away for better illustration of parts. Fig.

2 is a plan View of the same, partly broken away, and with the covering of the casing removed. Fig. 3 is a cross-section of the same on the line a: L of Fig. 2 with the frame partly broken away. Fig. 4 is a perspective view of one of the atomizers. Fig. 5 is a section of the upper feeding device on the line g/ y of Fig. 1. y Fig. 6 is a section of the lower roll-mounting of the feeding device on the line s 2 of Fig. l, and Fig. 7 is a detail vin front elevation of the aperture-closing plates for the casing.

1 represents the frame of the machine, and 2 the casing, through which the stock (shown as a piece of picture-molding and represented at X) is adapted to be caused to pass. 'The casing may be formed in any suitable manner. I have shown its ends as consisting of plates 3 4, secured to the frame and having lugs 5, through which they are connected by bolts 6, the top of the plates being connected by'a spannerplate 7, secured to the end plates. Side plates 8 9 are hinged to the Spannerplate by hinges 10, handles 11 being provided for raising the side plates, and thereby exposing the interior of the casing for inspection or adjustment and attention of the parts. The casing is preferably provided with glass inclosing frames 12 in the side plates through which the operation of the device may be observed, the frames being hinged on hinges 13 for access to the interior of the casing, a catch 14 holding the frames closed.

Preferably at each side of the frame of the machine there are one or more receptacles 15, suitably placed, adapted to contain the composition or material with which it is desired to coat the stock. I have shown three of these receptacles at each side of the frame, although it is obvious that any suitable number may be employed, dependent on the various kinds of material it is desired to use in coating or finishing.

A suitable number of atomizers 16 are arranged, preferably, at each side of the machine. These atomizers are preferably mounted on posts 17, takinginto apertures 18 in the frame and adjustable therein to height and about the aXis of the posts, and secured in adjusted position by means of bolts 19. Each of the posts supports a shelf 20, having a plate 21 adjustable thereon, as by a bolt 22, taking through a slot 23 in the plate and into threaded apertures 24 24 at the respective ends of the shelf. The shelf is preferably overhanging, with the plate arranged to be secured to the post end or overhanging endV of the shelf for regulating the overhanging of the atomiZer-head. The plate has a trunnion 25 thereon, about which a nozzle-support 26,

IOO

forming an atomizer-head, is adapted to be adjustably clamped in suitable manner. The atomizer-head comprises two branches 27'28. A coating-conducting tube 29 is adjustably secured in the branch 27, as by being shifted longitudinally in an aperture therein and secured in place by a set-bolt 30. A compressed-air or blast conducting tube 31 is longitudinally adjustable in the branch 28, as bypassing through an aperture therein, and secured in adjusted position by a set-bolt 32. The tubes 29 31 are respectively provided with removable tips 33 34, thelongitudinal adjustment of the tubes permitting the'orices in the ends of the tips to be placed in relatively suitable positions for creating vthe proper spray and the adjustment of the head permitting the spray to be projected in suit- 1 able direction for proper application to the stock.

35 is a pressure-tank into which compressed air or other pressure medium may be introduced through a pipe 36, a cock 36 shutting olf power to all atomizers, liexible tubesor pipes 37 connecting the tubes 31with the interior of the pressure-tank, suitable cocks 38 being provided for regulating the passage of pressure to the various tubes 31 or entirely:

cutting them o selectively, as may be desired. Providing the pressure-tank from which the various tubes are fed insures uniformity of pressure to all the pipes.

The receptacles 15 have pipes 39 taking into them and projecting almost to the bottom thereof, the pipes 39 communicating with the respective tubes 29, preferably by a Hexible' connection 40.

The pipes 39 are supported in covers 41. Each of the receptacles is also provided with a cock 42 for emptying the receptacle when desired.

The material with which it is desired to coat the stock usually consists of mixtures Whose ingredients have different specific gravities, and in order to preserve the ingredients in properly mixed state and convey the same properly mixed through the atomizers I form connection between the pressure-tank 35 and the receptacles for conducting the fluid under pressure from the pressure-tank into thematerial contained in the receptacles, as by means f of a pipe 43, communicating with the interior of the pressure-tank and having branches 44 taking into the several receptacles and comtravel of Vstock and arranged so thatithe feed -of eachatomizer may be regulated or entirely discontinued, if desired. In my improved device stock of various kinds may be passed through the machine for receiving its finishz'. e., being coated with various substances which it may be desired to apply to it- Whether such coating or finish be applied direct to the stock or be an intermediate or final coat. Thus my improved device may be employed in applyingshellac,varnish, bronze, or various materials with `which it is desired to coverthe stock. l

For passing the-stockthrough the casing of the machine I prefer to mount the feeding agency 'outside the casing -at the feeding-in end of the machine. Thus in the present exemplilication of Vmy invention I show a feeding-in table 51, in which a lower roll 52 is supported, as on a shaft 53, having concentric studs 54 55 and an eccentric journal-56 for the roll, the concentric studs being mounted,I respectively, in bearings 57 58 in the table, the shaft being rigidly held by a nut 60, clamping the shaft to the table. Vhen the shaft is turned, the eccentric mounting of the roll causes the roll to project more or less above the table.

61 62 are standards extending above the table and secured to the table-frame. A shaft 63 is secured in the standards in bearings 64 65. A gear 66 is journaled on the shaft and is held against endwise movement thereon between the bearing and a collar 59, secured to the shaft. The gear has an elongated hub 67, to which is secured an operating device, as a pulley 68.

69 is a yoke journaled inbearings 70 71 on stud-journals 72 73 of the bearings 64 65. The gear 66 meshes a gear 74, journaled on a stud 75 on the yoke. The gear 74 meshes an operating-gear'76, secured to a feed-roll shaft 77, jou rnaled in bearings 78 79 of the yoke 69. The feed-roll shaft carries a feed-roll 80, suitably secured thereto and adjustable thereon, this'feed-rollbeing preferably a cushion feedroll, the feeding-body of the roll being preferably composed of rubber. For accommodating different thicknesses of stock the yoke has a link 81, pivotally secured thereto at each side thereof, each of the links having a bolt V83, taking through a slot 84 therein and into the table-frame for positioning the upper feedroll'relatively to the table.

`The end walls of the casing are provided with openings 85, through which the stock 89 vmay also be provided, being adjustable by havingl bolts 90 take through slots 91 in the plate 89 and into the end wall of the casing.

A plate 92 takes under the plate 89.

In employing various kinds of coating for the stock dust is created inside of the casing. For removing dust I provide, preferably, each end of the casing with an opening 93, with each of which a pipe-94, in which there may able laterally on the table by means of T-bolts 97, passing through slots 97 in the gages and into T-slots 98 in the table and held in place by nuts 99. These gages guide the stock into the machine and the stock is fed through the machine preferably by having the following piece of stock take against the preceding piece and pushing it through. In my improved device I'have provided the feeding agency outside the casing, so that the finish on the stock may not be injured by devices contacting therewith after application of the coating. If desired, the table inside the casing majT consist of a ridge-plate 100, having ridges 101, upon which the stock may ride. In practice many of the compositions for coating are composed of viscous substances liable to offer resistance to the passage of the stock through the casing if the stock take directly against a plane table and the table receive a coating of the substance. In order to reduce this resistance to the minimum, I have provided the ridges 101 in the table. A feeding-out table 102 may also be provided and preferably have the ridges thereon.

In my improved device compositions of different substances, colors, or kinds may be employed in the various receptacles for producing various and different effect-s at one operation or passage of the stock through the machine, or the atomizers near the feedingin end of the casing may be employed "for providing the stock with a coarser or under coating, while those near the feeding-out end may provide a final or finishing coating at one passage of the stock through the machine, whereby passages of the stock through the machine may be saved. In my improved device also the atomizers may be angled with relation to each other and pointed toward the stock from various heights and directions (see exemplilication in the drawings) for proper application of the various coatings to the various parts of the stoel; in the passage of the latter through the machine.
